I've simulated radiative capture of thermal neutrons on Cd-113 and recorded the energy of each gamma ray produced from deexcitation. I used Geant4-10.0.2/G4NDL4.4 and the G4NeutronHPCapture model. The result is shown in the attached histogram. Although I do get a number of expected lines (http://www.nndc.bnl.gov/capgam/byn/page128.html), they occur with the wrong yield and alongside other unexpected lines. To make things worse, there is a continuum of gammas beneath the discrete lines. I have a several questions:
Why is this incorrect result produced? Am I missing something with the physics settings? If not, are the models likely to improve in the near future?
